To ur/Z whom, t ntctyconcern:

Be it known that L'AnrI-IUR E. COLGATE, a citizen of the United States, residing at the city, county, and State of New York, (postoifice address No. 251 West One Hundred and Twenty-ninth street,) have invented certain new and useful Improvements in Picture Apparatus, of which the following is a full, clear, and exact description.

My invention relates to picture apparatus, and the object of my invention is to provide a means for illustrating, for example,-one complete scene or View, with means for at once showing to the user relatively enlarged detail views of certain points of important interest, which, because of the scale upon which the main view is taken, cannot be fully comprehended orclearly seen in such view. rFor example, in the drawings I have shown a mountain scene in a mining district. At several points shaft or tunnel openings appear. In this particular instance, these openings may be assumed to be the points of especial interest, and the user has merely to turn back the leaf, the free edge of which lies closest to the opening which he is particularlyr interested in, whereupon therey is exposed beneath the leaf just turned back an enlarged view of said detail. This idea may be extended to many scenes and views, the main illustration continuing over two or more superposed leaves when the same are closed.

In the drawings, Figure l is a plan view of an open booklet, the cover-leaf of which is turned back to expose the illustrated portion showing the main view. Fig. 2 is a similar view, with the cover-leaf partially broken away, and showing a portion of the main View as Well as a relatively enlarged view of one of the details. Fig. 3 is anedge elevation of the parts shown in Fig. 2.

A is the back cover; A is the front cover. These covers may or may not be employed, as desired, but furnish a protection for the picture apparatus, and also furnish a space for the publication of any description it may be desired to employ with reference to the particular scene depicted.

B, C, D, E and F are a plurality of connect ed superposed leaves, the free edges of which are non-registering- G represents the backing or binding for the connected edges of said leaves.

l, 2, 3 and 4 illustrate points of particular interest. The main scene exposed (when the several leaves are turned down) is a mountain may lie so closely view or landscape. The points of particular interest represent shaft openin s-or tunnels extending into the earth. pon turning back the several leaves D, E and F, for example, as shown in Figs. 2 and 34, a relatively enlarged view C is uncovered, which gives to the reader a comprehensive illustration of the detail represented at 2. It is preferable to have a portion of the picture at the edge of each overlying leaf reproduced on the underlying leaf and extending slightly under the edge of the first-mentioned leaf, for example, as indicated in the reproduction of detail numbered 2 on leaf Cin Fig. 2. The purpose of this is to prevent any substantial impairment of the view as a whole inthe event the edges of the several leaves might be curled up slightly. This, it will be understood, is merely a preferable construction, as of course that portion of the picture on any one leaf might stop abruptly at the edge of the overlying leaf. While the other detail views are not shown in the drawin s, obviously the relatively enlarged view. of the detail numbered 1 would be exposed upon lifting and turning back the leaf C; andthe detail at 3 by turning back the leaf Erhand the detail at 4l by turning back the leaf F.

It will be seen that in the preferable form of my invention, the edge of a particular leaf adjacent to the detail, the enlarged View of which it covers, that it acts as a key or index to the particular view underneath 4the same. For example, the free edge of the leaf D lies closely adjacent to the tunnel opening 2. By turning back this leaf D, the reader will lind that the relatively enlarged illustration C shows, in a comprehensive manner, the shaft' opening 2 with a track entering the same, with a car on said track. As suggested, it is immaterial what the main View is, since, whatever it may be, Y

the scale may be such as to make it necessary to illustrate details on an enlarged scale, and this may be done very effectively and compactly by the means above described.

1. In a picture apparatus a plurality of connected superposed leaves the free edges thereof being non-registering, an illustration extending over the exposed surfaces of two or more of said leaves, and a relatively enlarged view of a detail of such illustration located on such a part of one of said leaves as is normally covered by another.

2. In a picture apparatus a plurality of IOO connected. superposed leaves the -free edges thereof being non-registering, an illustration extending over the exposed surfaces of two or more of said leaves7 and a relatively en larged view of a detail of such illustration lo# Gated on sueh a part of one of said leaves as is normally covered by another, the 'free edge of the over-lying leafv being1 located adjacent to the detail, the enlargement of which is to be exposed by turning back said leaf.

3. In a picture apparatus, a plurality of connected superposed leaves, the free edges thereof being non-registering, an illustration extending over the exposed surfaces ol two or more of said leaves, and a relatively en larged view of a detail of such illustration carried by one of said leaves and covered when the leaves are in position to expose the main illustration.
